DIACETYL

Diacetyl is an aroma compound known for its rich, buttery, and creamy character. Its scent profile is typically described as warm, sweet, and dairy-like, strongly reminiscent of butter, cream, and freshly baked pastries, with a soft caramelized nuance that contributes to its gourmand quality.

The material usually appears as a yellowish liquid with low viscosity, and is appreciated for its very powerful aroma, even at extremely low concentrations. Its character is intense and immediately recognizable, which means it is typically used in very small amounts within fragrance or flavor compositions.

In practical fragrance work, Diacetyl may be used to add buttery and creamy facets to gourmand-style accords, especially those inspired by caramel, pastry, or dairy-like notes. It blends well with vanilla, caramel accords, lactones, maltol-type ingredients, and sweet gourmand materials, making it useful in sweet, dessert-inspired fragrance compositions.
